To find detailed information about aircraft restraining devices, which manual is referenced?

The reference A, NA 17-1-537, is the correct manual for finding detailed information about aircraft restraining devices. This manual specifically covers the technical data and procedures necessary for the proper operation and use of aircraft restraints, ensuring safety and compliance during aircraft handling and operations. NA 17-1-537 provides comprehensive guidelines that include installation, securing methods, maintenance, and operational limitations of these devices, making it an essential resource for personnel involved in aircraft preparation and handling.

The other references may pertain to different aspects of aircraft operation, maintenance, or procedures, but they do not specifically focus on the detailed information related to aircraft restraining devices. Therefore, while they may provide valuable information in their respective areas, they do not contain the targeted data one would seek regarding the use and handling of restraining devices.
